I am working on getting networking working correctly on a cluster of 14 virtual servers at a customer site. 11 of them work fine for routing and 3 don't work correctly for their administrative network (172.28.56.0). All are running Windows Web Server 2008R2.

Default gateway is set on the production network (172.28.58.0) and not on the administrative network (handled with persistent static routes).

On a working server, route print gives me the following (MACs redacted)

I am at a complete loss why the non-working servers have no On-link route for 172.28.56.0. Does anyone have any suggestions on what I should be looking at to figure this out? Also, I do have "physical" access to the console if needed through vSphere Client.

@smccloud For future reference, the ideal solution would be to simply flag your own post for moderator attention (assuming you can, I'm not sure if there's a rep requirement for that), or simply wait. It's not that it's a bad question for Super User -- There's a lot of overlap between the communities -- But in the long run, it simply fits better on Server Fault. That all being said, I hope you get the issue worked out!
